"Hewlett-Packard sold WebOS to LG Electronics, which will re-purpose it for its smart TVs."
It is very interesting. What's so good in WebOS for Smart TV application that Android is unable to offer?
Firefox goes mobile is interesting. There might be a lot of attention and developers would like it. Ubuntu tablet will draw a lot of attention too. I wonder when I can download and build my own Ubuntu mobile or Firefox mobile.

The story of the collapse of PalmOS will make a cautionary business case lesson for anyone in the world of Internet innovation. How did the leading PDA interface manage to decline into a "hot potato" for HP to hand off?
